CAAD 교육에 있어서 디지털 체인 패러다임의 수용방법론에 관한 연구

This study starts from a critical thinking that the meaning of digital chain may or should be redefined in order for the research in computer aided architectural design(CAAD) to situate itself within the realm of education for architecture. The meaning of digital fabrication has confused with the characteristics of the model manufacture only in a sense. Thus, we criticize the nature of digital fabrication revealed in digital chain for design education, then move to its definitions, and finally suggest a framework of education in CAAD. We analyze the example, course of ETH CAAD lab, and finally formulate the ideal and actual mythology of expansive digital chain curriculum for education. In order to the digital chain to become a new paradigm of CAAD education, we propose the optimized process for the digital chain. The means optimized is that it has high degree of freedom of design procedure in boundary digital chain accordingly it induces expansive and creative design issue for constant evolution.

마이크로-플레이트릿 광간섭 안료를 이용한 태양광용 고투과 컬러 유리에 대한 연구

신동윤(Dong-Youn Shin),이진섭(Jin-Seob Lee),신창수(Chang-Soo Shin),성창환(Chang-Hwan Seong) 대한기계학회 2020 大韓機械學會論文集B Vol.44 No.7

인위적인 기후 변화를 유발하는 이산화탄소 배출량을 줄이기 위해 제로에너지 건축이 법제화 되었으나, 종래의 건물 일체형 태양광 모듈은 태양광 발전 효율을 최대화하기 위해 흑색으로만 제작되었기에 심미성을 중요시하는 건축물의 외관에 적용하는데 장애물이 되어왔다. 본 연구에서는 마이크로-플레이트릿 광간섭 안료를 이용한 태양광용 고투과 컬러 유리의 제작에 대해 소개하도록 한다. 광간섭 안료의 함량이 광학 투과율에 미치는 영향을 조사함으로써 색상을 구현하는데 요구되는 광간섭 안료의 최소 함량을 결정하였다. 3wt% 광간섭 안료 함량의 컬러 유리로 태양광 모듈을 제조하고 전기적 특성을 측정하였다. 마이크로-플레이트릿 광간섭 안료의 사용은 진공 증착 다층 박막 적층법으로 색상을 구현하는 방식보다 저렴한 인쇄 공정을 적용할 수 있기 때문에 제조 비용을 절감할 수 있으며, 발전 효율도 기존 태양광 모듈의 76.15%에 이르렀다. The construction of zero-energy buildings will become mandatory to curtail the amount of CO₂ emissions, which lead to anthropogenic climate changes. However, conventional building-integrated photovoltaics are monotonously black in color to ensure high photoconversion efficiency. Hence, this has been a hurdle in aesthetically decorating the skin of a building. In this study, a micro-platelet light-interference pigment is explored for the fabrication of a highly transparent color glass for photovoltaic applications. The impact of pigment concentration on optical transmittance is investigated and the minimum pigment concentration for realizing a vivid color is determined. A photovoltaic module is fabricated using a color glass with a pigment concentration of 3 wt%, and its electrical properties are measured. The use of a micro-platelet light-interference pigment lowers the fabrication cost (by using a printing process) when compared to that of a costly color glass with multi-layered thin films deposited in vacuum. Furthermore, the relative photoconversion efficiency of the proposed method when compared to a conventional photovoltaic module is as high as 76.15 %.

Inkjet printing technology, especially based on a piezo Drop-On-Demand(DOD) inkjet print head, has been recognized as one of versatile and low cost manufacturing tools and hence numerous R&D activities have been performed to transfer it to production lines in many industrial fields. Although it has been employed to day-to-use desktop inkjet printers for many years, the influence of driving conditions, especially its driving voltage waveform, has not been fully understood because of the inherent nature of complex multi physics in a piezo DOD inkjet print head. This complex nature of a piezo DOD inkjet print head has led researchers and developers to implement computationally expensive numerical methods. In this study, a fully mathematical model for a cylindrical type piezo DOD inkjet print head is proposed and its analytic results are compared to experimental results. Finally, the possible causes of errors and the advantage of the proposed mathematical model are discussed.

China has a long-standing respect and care for the old historical tradition, the elderly in history has a strong and authoritative representatives, but with the economi cand social development, the elderly, social status, economic status and physical condition of the decline in the elderly gradually evolved into the vulnerable groups of society, their material and spiritual aspects of the legitimate rights and interests of more vulnerable to violations. As China entered an aging society, the problems caused by theelderly are endless, and how to better protect the legitimate rights of older persons through legal channels, also caused widespread concern in society as a whole. While protecting the legitimate rights of older persons is a matter of the field is very wide and complex variety of situations and global issues. It is a complex social system projectand not relying on one or several laws and regulations, or one of several departments will be able to solve the problem on the basis of the "Protection of the Rights and Interests of the Elderly" to further improve the elderly protecting the rights of the legal system, while other aspects of social old-age security, health care and community careto older persons more care.

AI의 역할과 활용: 건축 디자인에서 ChatGPT와 DALL.E의 통합적 접근

신동윤(Shin, Dong-Youn) 대한건축학회 2024 대한건축학회논문집 Vol.40 No.2

This study delves into the use of generative AI, specifically ChatGPT and DALL.E, in architectural design, focusing on their abilities to comprehend architectural blueprints, interpret sketches, and generate 3D images. It represents pioneering research in integrating ChatGPT into architecture, offering fresh insights. The methodology consists of two phases: the first phase assessed ChatGPTs capacity to interpret and provide feedback on architectural sketches, revealing its potential for creative input but limitations in understanding complex designs; the second phase examined DALL.Es effectiveness in generating 3D images from textual descriptions, where it showed promise in producing contextually relevant images, albeit with some challenges in detailed architectural understanding. This study finds that while these AI tools can enhance initial design stages with innovative suggestions and preliminary analyses, they cannot fully replace the nuanced judgment and expertise of professional architects. However, this research highlights ChatGPTs relevance for specific architectural tasks, enhancing their efficiency. One limitation is the reliance on a single building design, potentially limiting the scope of architectural challenges examined. Future studies should incorporate diverse designs for broader validation. In summary, integrating generative AI into architectural design shows promise for boosting creativity and efficiency, although these tools are not yet equipped for complex architectural planning. They lay a valuable foundation for future advancements in this field.

Social costs analysis seeks to reveal the environmental effects of transportation policy. It delivers a sense of the effects of the public s daily travel and the costs that are or would be incurred from individual trips. Moreover, the accumulated total number of trips will uncover the effects of travel on society. This article shows the quantitative analysis of the economic outcomes of travel using social costs estimation methods. In order to support urban planning tasks, this research implemented analysis tool for social costs estimation by travel behavior. For a case study, a jave based application which can convert people s trip data into social costs is developed. the application used for simulating student-housing effects by estimating social costs changes. The analysis included the attributes, building scale and locational changes of the student housing as well as transforms of the students trips.
